Description
The technical field is as follows:
the invention relates to a mariculture net cage, in particular to an anti-flow net cage system with a separable bottom net and side nets.
Background art:
the netting of the net cage can be divided into a side net and a bottom net according to the position relation, and the side net and the bottom net are connected into a whole to form a closed culture space. Typically, the bottom net of conventional net cages is not detachable, as shown in fig. 1. With respect to the technical development of seawater net cages, the following problems are worth paying attention:
firstly, cleaning a side net and a bottom net:
larvae and spores of a large number of marine organisms and microorganisms can move along with the flow and are attached to the sea wave-resistant net cage, so that the water body exchange inside and outside the net cage is reduced, the culture environment is deteriorated, the diseases of fishes cultured in the net cage are frequent, the resistance and the drift of the net cage are increased, the abrasion among the net cages of the net cage is increased, and the service life of the net cage is shortened. Therefore, the netting needs to be cleaned periodically.
There are various methods for cleaning the net, including a manual scraping method, a mechanical cleaning method, and the like. However, in any method, the cleaning difficulty of the bottom net is often greater than that of the side net. Especially when the circumference and height of the netting are large, i.e. the bottom net is located at a deep position from the sea surface and has a large area, the difficulty of cleaning the bottom net in the sea is greatly increased.
II, volume loss rate of the netting:
the netting system mainly encloses a culture water body for the activity of culturing fishes. If the flow rate of the seawater is high, the netting often floats indefinitely and gathers inwards, so that the culture space of the net cage is reduced, the moving range of aquatic products is reduced, the oxygen content in water is reduced, the water quality is reduced, and further various diseases are induced.
The largest influence of the flow velocity of the seawater on the net cage is found by domestic experimental research, the volume of the net cage is reduced, and when the flow velocity is 0.5m/s, the volume loss rate of the net cage is about 30 percent; when the flow velocity is 1.0m/s, the volume loss rate of the net cage is about 50 percent; when the flow speed is 1.5m/s, the volume loss rate of the net cage is about 70 percent. Therefore, how to reduce the volume loss of the net cage is one of the key technologies for improving the single yield of the net cage culture.
At present, in order to avoid that the netting extrudes the cultured objects together due to the action of water flow, a series of sinkers are usually tied at the bottom of the netting according to a certain interval, or an annular support ring is put into the net cage, and the support ring sinks into the bottom of the net cage, so that the netting can be prevented from gathering inwards. However, when the net is replaced, cleaned or pulled to collect fish, a diver needs to dive to the bottom to pull out the sinker from the water surface before collecting the net or take out the support ring, so that the labor time is increased, the cultivation cost is increased, and the working efficiency is lower.
Thirdly, replacing the netting in the culture process:
in order to remove attachments on the net and adapt to the growth requirement of the fish body, the net needs to be replaced at proper time, the meshes are enlarged, and the water body exchange inside and outside the box body is improved. Generally, the box body is cleaned and replaced once every 1-3 months. The old netting is replaced on the sea, particularly under the working condition of windy and heavy wave, and the new netting needs to be installed, so that the weight of the netting of the large net cage reaches several tons, the labor intensity is high by manual operation, and the personal safety of a culture worker is poor. Therefore, tools and measures for assisting the replacement of the netting are to be developed, so that the netting replacement operation is simpler and more convenient.
Therefore, a novel net cage system is needed to be developed, so that the bottom net can be conveniently cleaned, the net volume loss rate is low, the net can be conveniently replaced, the labor time of various breeding operations is reduced, and the working efficiency is improved.
The invention content is as follows:

The specific implementation mode is as follows:
referring to the attached drawings (the anchoring foundation and the net cage system are connected by anchor chains as the prior art, and are not marked in the attached drawings):
the anti-current net cage system with the bottom net and the side net which can be separated comprises an anchoring foundation, a net cage frame 1 and a side net 2 of a net, wherein the bottom net 7 is formed by binding the net on the bottom net frame 4, and the bottom of the side net 2 is bound on the outer side of the bottom net frame 4 to form a closed culture space together with the bottom net 7; a plurality of steel wire ropes 11 are bound on the bottom net frame 4, a plurality of interconnected sleeves 8 are sleeved on the steel wire ropes 11, the steel wire ropes 11 sleeved in the sleeves 8 are arranged in the net cage, and the other ends of the steel wire ropes 11 are moored on the net cage frame 1, so that the anti-current net cage system with the bottom net and the side nets being separable is formed.
The anti-flow cage system with the bottom net and the side net separable from each other will be further described and explained below.
The structural construction of the anti-flow net cage system comprises the following steps:
the bottom net frame 4 is formed by uniformly and symmetrically welding a plurality of vertical and oblique connecting plates 6 between two same circular ring pipes, a plurality of mooring rings 5 are also uniformly and symmetrically welded between the two circular ring pipes, and the outer diameters of the circular ring pipes are equal to the diameter of the side net, as shown in fig. 2. The bottom net 7 is formed by binding a netting on a ring pipe of the bottom net frame 4, as shown in fig. 3. The lacing lines at the bottom of the side net 2 and the netting are bound on the outer side of the bottom net frame 4 and form a closed culture space together with the bottom net 7, as shown in fig. 4.
Have certain distance between two ring pipes on end net frame 4 for end net frame 4 has certain weight and great intensity, and it makes end net more smooth-going on the one hand, and on the other hand has restraint and the effect of holding back on the other hand to the side net, effectively maintains the culture space of box with a net.
The bottom of the side net 2 is bound on the outer side of the bottom net frame 4, and the distance between the two circular ring pipes on the bottom net frame 4 is the lap joint length of the side net 2 and the bottom net 7. The side net 2 and the bottom net frame 4 are convenient to connect and disassemble, and flexible assembly and disassembly as required in subsequent various breeding operations are facilitated.
The bottom net and the side net of the provided net cage system can be assembled and disassembled mutually, the thinking mode that the bottom net and the side net of the traditional net cage are woven at one time to form a whole body is broken, the cultivation requirement of a closed water body formed after the bottom net and the side net are assembled can be realized, the difference of the bottom net and the side net can be reflected, various cultivation operations are facilitated, and the reasonability and the practicability are obviously achieved.
The structure of the net cage with the bottom net installed on the net cage frame and the side net is shown in fig. 10. The bottom net and the side net can be assembled and disassembled as required, various operations including cleaning the bottom net are convenient, and a new idea is provided for the design of net cages and nets.
After the bottom net and the side net can be assembled and disassembled mutually, the operation modes of operations such as netting cleaning, net changing, cultured fish box separating, cultured fish harvesting and the like can be changed correspondingly, and the improvement of the working efficiency of various culture operations is promoted.
The sleeve 8 is a straight pipe made of metal or plastic, the inner diameter of the sleeve 8 is not less than 3 times of the outer diameter of the steel wire rope 11, two connecting rings 9 are symmetrically arranged at two ends of the sleeve 8, and the connecting rings 9 at the end parts of the sleeve 8 are bound through a rope 10, so that the sleeve 8 can be connected end to end, as shown in fig. 5 and 6.
The length of all sleeves 8 in the proposed netting fixing device is the same. Generally, the length of the sleeve 8 may be determined based on the approximate average of the mesh depth into a plurality of equal parts, such as the length of the sleeve 8 in fig. 7 approximately 1/4 of the mesh depth.
The function of the sleeve 8 is: when the netting is inclined and gathered inwards when being impacted by ocean current, the steel wire rope 11 tightly contacted with the netting is inclined synchronously, the sleeve 8 sleeved on the steel wire rope 11 restrains and controls the inclination amplitude of the flexible steel wire rope 11, so that the inclination slopes of the steel wire rope 11 in the sleeve 8 are the same up and down, the random flexible deformation of the netting is greatly reduced, and the volume ratio of the netting is maintained to the maximum extent.
Each mooring ring 5 of the bottom net frame 4 is moored with a steel wire rope 11, a plurality of sleeves 8 which are connected with each other and the total length of which is slightly smaller than the depth of the netting are sleeved on the steel wire ropes 11, the steel wire ropes 11 sleeved in the sleeves 8 are arranged in the net cage, and the other end of the steel wire ropes 11 is moored on the net cage frame 1 after being straightened, as shown in fig. 7-9 and fig. 11-13. It can be seen that the number of the steel wire ropes 11 is equal to the number of the evenly arranged mooring rings 5, the number of the evenly and symmetrically welded mooring rings 5 on the bottom net frame 4 is not less than 4, that is, the number of the steel wire ropes 11 shared in the net cage system is not less than 4, and the volume ratio of the netting can be effectively maintained. As in fig. 7, 8 steel cords 11 are used.
However, when the number of the steel wire ropes 11 uniformly arranged around the inner side of the netting is too small, the influence on the random ocean current is limited, so that the number of the steel wire ropes 11 commonly used in the net cage system is not less than 4.
The anti-flow characteristic of the anti-flow net cage is expressed as follows: the rigid bottom net frame 4 and the steel wire rope 11 sleeved into the sleeve 8 maintain the net volume rate together, and the net volume loss rate under the action of ocean currents is reduced.
II, netting materials of the bottom net and the side net:
the netting material of the side net 2 is synthetic fiber netting, such as polyethylene netting, polyamide netting, ultra-high molecular weight polyethylene fiber netting and the like, which is a traditional netting material and has the characteristics of relatively common use and low cost; the netting material bound on the bottom net frame 4 is metal netting, such as zinc-aluminum alloy wire, galvanized steel wire, copper-zinc alloy wire, tortoise shell net, titanium net, etc., which has stronger anti-flow ability and anti-pollution ability, longer service life than synthetic fiber netting material, and can be recycled.
Because the distance between the net cage bottom net and the sea level is relatively large, the difficulty of cleaning the bottom net in the sea is large, after the bottom net adopts the metal netting, the anti-fouling capability is strong, marine fouling organisms are difficult to attach and grow on the metal netting, and the cleaning frequency can be greatly reduced. Therefore, after the bottom net of the net cage adopts the metal netting, the number of times of cleaning the bottom net can be greatly reduced, and only the side net is cleaned, but the automatic cleaning of the side net in the prior art is easier to realize. Different portions in the provided net cage system adopt different netting materials, and a new idea is provided for fully exerting the advantages of various materials.
Although the bottom net is made of the metal netting, the metal netting is high in one-time investment, on one hand, the metal netting is long in service life and can be recycled, and on the other hand, the cleaning difficulty and frequency of the bottom net are reduced, so that the cost performance is still high in comprehensive consideration, and the metal netting has popularization and application values.
Thirdly, assembling the net cage:
the bottom net and the side net of the conventional net cage are connected with each other to form a closed culture space, as shown in fig. 1. The difference between the net cage system provided by the invention and the traditional net cage is as follows: the bottom net and the side net need to be assembled into a whole; a steel wire rope 11 is moored and connected between the bottom net frame and the net cage frame, and the sleeve 8 is sleeved on the steel wire rope 11.
The assembly process of the proposed cage is as follows: firstly, a bottom net 7 is formed by binding a netting on a ring tube of a bottom net frame 4, then the netting is bound on the outer side of the bottom net frame 4 based on a lacing line at the bottom of a side net 2, and a closed culture space is formed between the side net 2 and the bottom net 7; the steel wire ropes 11 are bound on the mooring rings 5 on the bottom net frame 4, the steel wire ropes 11 are arranged in the net cage, the length of the steel wire ropes 11 can be 1.5 times of the depth of the net cage, and the other ends of the steel wire ropes 11 are temporarily loosely tied on the net cage frame 1; the upper parts of the side nets 2 are connected and fixed on the net cage frame 1, so that the bottom net 7 is gradually sunk into the sea under the action of weight and the side nets 2 are straightened; and then the steel wire ropes 11 moored on the net cage frame 1 are unfastened one by one, sleeves 8 which are connected end to end and have the total length slightly smaller than the depth of the net are sleeved on the steel wire ropes 11, the steel wire ropes 11 are bound on the net cage frame 1 after being straightened, and the steel wire ropes 11 are positioned in the net cage after the installation is finished.
Fig. 2 to 13 show details of the assembling process of the net cage. The assembled structure of the net cage is schematically shown in fig. 11.
Fourthly, the pulling-up process of the netting:
if the netting needs to float upwards in the process of changing the netting and harvesting the cultured fish. The net-pull-up process of the proposed cage system is as follows: the steel wire ropes 11 which are arranged in the net cage and connected with the net cage frame 1 are firstly untied, the sleeves 8 on the steel wire ropes 11 are pulled up and removed, then the steel wire ropes 11 are pulled up evenly and symmetrically by using shipborne equipment, the bottom net frame 4 moves up gradually under the pulling action of the steel wire ropes 11, the bottom net 7 and the side net 2 which are attached to the bottom net frame 4 also move up gradually until the bottom net frame 4 is pulled to be close to the net cage frame 1, and then various breeding operations including changing netting can be carried out.
The steel wire rope 11 with higher strength is moored between the bottom net frame 4 and the net cage frame 1, the sleeve 8 is sleeved on the steel wire rope 11 to fix the netting at ordinary times, and the steel wire rope 11 plays a role of a stress point when the netting is pulled up, so that the possibility of subsequent mechanical net collection is provided.
The weight of the bottom net 7 and the side net 2 is transferred to the net cage frame 1 through the lacing lines in the net, i.e. the steel wire ropes 11 do not bear the weight of the net.
Different cage frame sizes, different numbers of mooring rings 5, different lengths of sleeves 8 may be used according to actual requirements, and several embodiments are described below.
Example 1: as shown in fig. 2 to 13, 8 mooring rings 5 are uniformly and symmetrically arranged on the bottom net frame 4, 8 steel cables 11 are correspondingly used and moored between the bottom net frame 4 and the net cage frame 1, the length of each sleeve 8 is about 1/4 of the net depth, and the net cage uses 32 sleeves 8. The structure of the device is shown in fig. 11 after installation.
Example 2: 12 mooring rings 5 are uniformly and symmetrically arranged on the bottom net frame 4, 12 steel wire ropes 11 are correspondingly used and moored between the bottom net frame 4 and the net cage frame 1, the length of each sleeve 8 is about 1/3 of the net depth, and the net cage uses 36 sleeves 8.
Further embodiments can be derived from the above idea, which is not exhaustive here.
The attached drawings only show the situation of the circular floating net cage, and according to the proposed idea, a detachable bottom net 7 and a steel wire rope 11 sleeved into a sleeve 8 can be arranged in net cages with other shapes, which belong to equivalent modification and change of the technology, and are not described again here.
